A new fabrication process of pedestal waveguides based on metal dielectric composites of Yb3+ /Er3+ codoped PbO-GeO2 thin films with gold nanoparticles
(Elsevier B.V., 2018-12-01)
This work reports the signal enhancement of Yb3+/Er3+ codoped PbO-GeO2 pedestal waveguides due to gold nanoparticles deposited over the core layer. The pedestal structure was obtained by conventional photolithography and ...
Low-loss pedestal Ta2O5 nonlinear optical waveguides
(2019-01-01)
In this work, we investigate a pedestal tantalum oxide (Ta2O5) material platform for integrated nonlinear optics (NLO). In order to achieve low propagation losses with this material, pedestal waveguides with Ta2O5 cores ...
Production and characterization of Tm3+/Yb3+ codoped pedestal-type PbO-GeO2 waveguides
(Canadian Science Publishing, Nrc Research Press, 2014-07-01)
This work explores the production and characterization of pedestal-type active waveguides based on PbO-GeO2 (PGO) thin films codoped with Tm3+/Yb3+ rare earth ions. Silicon wafers containing around 1.7 mu m of SiO2 thickness ...

Influence of silicon nanocrystals on the performance of Yb3+/Er3+: Bi2O3-GeO2 pedestal waveguides for amplification at 1542 nm
(2018-01-01)
This paper reports for, the first time, the influence of silicon nanocrystals on the photoluminescence and optical gain of Yb3+/Er3+ codoped Bi2O3-GeO2 waveguides for amplification at 1542 nm. Pedestal waveguides were ...
